Description

Technical Field

[0001] This application relates to the technical field of clamps, and in particular to a winding wheel tapping positioning device. Background Technology

[0002] Some existing winding spools require tapping to facilitate subsequent mechanical installation. Current tapping equipment typically uses clamps, but these clamps, due to their small contact area and the application of compressive force, result in insufficient clamping tightness and may even cause burrs on the winding spool, rendering it unusable. Therefore, to address these issues, this application provides a winding spool tapping and positioning device. Utility Model Content

[0003] To address the aforementioned problems, this application provides a winding wheel tapping positioning device.

[0004] This application provides a winding wheel tapping positioning device, in which a platform plate is installed on the support of the tapping machine, and a three-jaw chuck structure is provided on the platform plate. The three-jaw chuck structure includes three clamping mechanisms that are driven by a worm gear disc structure. The clamping mechanism has a two-section structure, including a base clamping block that slides on the chuck, and an adjustable block that is bolted to the clamping block.

[0005] A notch is provided at the bottom of one side of the adjustable block. The notch applies an inward and downward squeezing force to the inner winding wheel, increasing the external friction force on the winding wheel.

[0006] By modifying the existing three-jaw chuck structure, the clamping mechanism is divided into two sections. One section still uses the worm gear for position transmission, while the other section has a notch at the bottom and is fixed to the first section with bolts. This allows for two clamping forces during clamping: one from the outside in and one from the top down, effectively improving clamping stability.

[0007] Preferably, the notch has an inclined structure in side view, and its end face is inclined downward.

[0008] Preferably, the three-jaw chuck further includes a housing fixed to the platform plate, and a worm gear disk is coaxially rotatably connected inside the housing. The worm gear disk has worm-shaped teeth welded on it, and the bottom of the clamping block is provided with clamping teeth that mesh with the worm-shaped teeth.

[0009] Preferably, a gear is engaged on the outer side of the worm gear disk, and a motor for driving the gear is provided on the outer side of the housing.

[0010] Preferably, the outer shell has a sliding groove that cooperates with the clamping block.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] By modifying the existing three-jaw chuck structure, the clamping mechanism is divided into two sections. One section still uses the worm gear for position transmission, while the other section has a notch at the bottom and is fixed to the first section with bolts. This allows for two clamping forces during clamping: one from the outside in and one from the top down, effectively improving clamping stability. Attached Figure Description

[0019] The following is in conjunction with the appendix Figure 1 - Figure 5 This application will be described in further detail.

[0020] Example 1:

[0021] A winding wheel tapping positioning device, as shown in the reference Figure 1 - Figure 5 A platform plate 2 is installed on the support of the tapping machine 1. A threaded hole 21 is opened at the bottom of the platform plate 2. A threaded bolt is connected in the threaded hole 21. The platform plate 2 is fixed on the support of the tapping machine 1 by the bolt. A three-jaw chuck structure is set on the platform plate 2. The three-jaw chuck structure includes three clamping mechanisms 4 that are driven by a worm gear disk 6-shaped structure. The clamping mechanism 4 has a two-section structure, including a base clamping block 41 that slides on the chuck, and an adjustable block 42 that is bolted to the clamping block 41.

[0022] A notch 421 is provided at the bottom of one side of the adjustable block 42. The notch 421 applies an inward and downward squeezing force to the inner winding wheel, increasing the external friction force on the winding wheel.

[0023] By modifying the existing three-jaw chuck structure, the clamping mechanism 4 is divided into a two-section structure. One section still performs position transmission with the worm gear 6, while the other section has a notch 421 at the bottom and is fixed to the first section with bolts. This allows for two clamping forces, one from the outside to the inside and the other from the top to the bottom, effectively improving the stability of the clamping.

[0024] The notch 421 has an inclined structure in side view, and its end face is inclined downward. The approximate size of the notch 421 is a triangular notch, but the specific size is selected according to the workpiece to be processed. The purpose of setting the adjustable block 42 in the device is to change different models to adapt to different sizes of workpieces to be processed.

[0025] The three-jaw chuck also includes a housing 3 fixed to the platform plate 2. A worm gear 6 is coaxially rotatably connected inside the housing 3. The worm gear 6 has worm-shaped teeth 61 welded on it. The bottom of the clamping block 41 is provided with a locking tooth 411 that meshes with the worm-shaped teeth 61. When the worm gear 6 rotates, the worm-shaped teeth 61 on it and the locking tooth 411 at the bottom of the clamping block 41 push against each other, thereby moving the clamping block 41 along the sliding groove 31 on the housing 3, thereby adjusting the clamping range of the clamping block 41.

[0026] A gear 7 is meshed on the outer side of the worm gear disk 6. A motor 5 is provided on the outer side of the housing 3 to drive the gear 7. A gear 7 group consisting of multiple gears 7 is provided at the output end of the motor 5. The purpose of this gear 7 group is to reduce speed and increase torque. The last gear 7 in the gear 7 group meshes with the worm gear disk 6, driving the worm gear disk 6 to rotate. The speed ratio between the motor 5 and the last gear 7 is 50:1.

[0027] The outer casing 3 has a sliding groove 31 that mates with the clamping block 41. The middle section of the clamping block 41 has protruding ridges on both sides. The sliding groove 31 has a structure that fits the clamping block 41 with a clearance. Lubricating oil is applied to the connection points to ensure smooth movement.

[0028] The foregoing description, with reference to preferred embodiments, illustrates an exemplary implementation of the winding wheel tapping positioning device provided by this disclosure. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, the protection scope of which is determined by the appended claims.
